Abstract
A 76-year-old man underwent distal gastrectomy and D2 lymph node dissection for type 3 advanced gastric cancer in June 2006. Postoperative pathological diagnosis was tub1, pT3, INFβ, ly2, v1, pN1, f-Stage IIIA, and the surgery was classified as curability B. Adjuvant oral UFT was given until January 2007 and the patient was followed up thereafter. In July 2007, a CT scan revealed a metastasis 2 cm in size in the S6 segment of the liver. RFA was selected as the treatment method in accordance with the patient's wishes, and the first session was performed in September 2007. Subsequently, metastases ≤3 cm in size developed asynchronously in the S4, S1, and S8 segments of the liver up to December 2009, and recurrence of ablated lesions was also observed. RFA was performed a total of six times during the approximately two years and three months since the time of the first session. No other distant metastasis or recurrence was observed during this period.
In the present patient, althtough asynchronous multiple liver metastases were observed in a short interval, RFA alone was thought to have had a certain degree of therapeutic effect because few metastases were present at any one time and all were ≤3 cm. In indicated patients, RFA may be effective for local treatment of liver metastasis of gastric cancer.
